Fully Automatic Vacuum Centrifugal Casting Machine–High-Volume Precision Casting Solution for Zinc Alloy Jewelry Boxes

This fully automatic vacuum centrifugal casting machine is purpose-built for high-volume precision casting of zinc alloy jewelry boxes and various exquisite packaging containers, with fully automatic cycle control + vacuum-assisted degassing + centrifugal precision filling as its core advantages—helping gift packaging manufacturers and cultural creative brands consistently produce high-quality jewelry boxes with clear surface patterns, precise opening/closing structures, and smooth finishes to meet the jewelry packaging and gift market's dual demands for detail expression and batch delivery efficiency.

Jewelry Box Structure Formed in One Shot–Accurately Reproduces Box Design & Decorative Details

Jewelry boxes typically consist of a lid and base, featuring surface relief decorations, hinge positions, and clasp structures—where dimensional accuracy directly affects opening/closing smoothness and closure tightness. This machine uses high-speed centrifugal force to distribute molten zinc alloy uniformly into every fine cavity detail, ensuring the melt tightly conforms to the mold texture—precisely reproducing box contours, decorative patterns, and mating structures with stable dimensions and smooth mating surfaces, significantly reducing assembly rework.

Vacuum-Assisted Degassing–Ensures Clear, Flawless Box Surface Patterns

Zinc alloy jewelry boxes often feature floral reliefs, geometric textures, brand logos, or decorative lines as surface details—where even minor porosity compromises product quality and subsequent plating results. Equipped with a vacuum system that actively evacuates residual mold gases before pouring, fundamentally eliminating pinholes, gas porosity, and surface pits—producing castings with smooth, refined metal surfaces immediately upon demolding, providing a perfect substrate for subsequent electroplating, sandblasting, or antique finishing.

Fully Automatic Cycling–Ensures Batch Quality Consistency & Boosts Daily Output

This machine integrates speed regulation, pouring, timing, and braking into a fully automated process—ensuring consistent casting parameters across every cycle. From the 1st to the 10,000th piece, surface pattern clarity and opening/closing structure precision remain stable, effectively eliminating batch-to-batch variation.

Built-In Furnace + Mold Concentric–Integrated High-Efficiency Production

Integrated independent furnace enables continuous melting-casting operation; mold concentric design ensures uniform metal distribution, guaranteeing wall thickness consistency and dimensional accuracy.

With fully automatic + vacuum precision casting as your dual drivers, your zinc alloy jewelry boxes gain market recognition for both decorative beauty and functional quality.
